Strategies

Melee

The strategy here is essentially the same as the boss version: keep circling, bait out his jumping or grab attacks and strike while he's recovering. However, there are two snow rats here that will aggro if you get too close to their hall. Let the demon notice you first and lure him to the more open ice patches for space, so you don't trigger all three.

Ranged

From the second ledge, position yourself so that his body is visible around the corner, then fire away. Alternatively, sprint to the tunnel the snow rats emerge from (in the far corner opposite from the Covetous Demon), then snipe him from behind the rocks (he can't reach you here).
